To all whom t may concern:

Be it known that l MARK B. WHITE, a citizen of the United tates, and a resident of Hanover, in the county of Jo Daviess and State of lllinois, have invented certain new and useful improvements in Winding-Machines, of which the following is a description, reference Ibeing had to the accompanying drawings, which form a part of my specification.

My invention relates to mechanism for winding the twisted yarn or thread, as it comes from the twisting mechanism, immediately upon boblbins which are so operated as to maintain the proper twist of the yarn as it is discharged by the twisting head or mechanismg thus providing a finished yarn ready for use on the looms and in the warping department.

The object of my invention is to provide mechanism whereby the finished `yarn or thread will be properly wound on the bobbins; the winding `of the` yarn being automaticallycontrolled, as will be more fully comprehended from the following detailed description of the accompanying drawings, lwherein Figure l is a plan view of the winding mechanism or unit with portions of the supporting frame or members broken away.

Fig. 2 is a. partial side elevation and sectional view of the mechanism, as disclosed in Fig. 1.

Fig. 3 s a detail View in plan of the yarncontrolling device of the mechanism, with the top plate or cover removed.

Fig. t is a detail view in side elevation of the yarn-controlling device shown in Fig. 3, and as illustrated in Fig. 2. i

Fig. 5 is a bottom plan view of the yarncontrolling mechanism, the bobbin-supporting spindle and supporting rods or frame being broken away.

Fig, 6 is a detail View, lin perspective, of one of the movement-controlling members.

Fig. 7 is a vertical sectional view taken on the line 7-7 of Fig. l looking in the: direction of the-arrows.

In practice, with my improved twisting and winding mechanisms or units, the units are usually arranged in batteries ;.the twisting units and the winding units in my` 1mproved machine being correlated or arranged in juxtaposition and all the units preferably driven from acoininon drive shaft, which may be'provided with graduated or stepped pulleys in order to permit the speed of the different units to be varied, commensurate with the speed of delivery from the carding machines to the respective units. The method of driving from a common driver or shaft may be the same as the method at `present in use; and as it forms no part of the present invention, the same has not been illustrated and need not therefore be described.

As the different units of the winding mechanism are all identical in construction and operation, a single unit is merely illustrated, with portions of a suitable supporting frame shown. rllhe yarn discharged from the twisting heads or units is passed through the hollow hub 10 in its passage to the bobbin 11 which is mounted on the spindle 12 so as to rotate therewith. rlhe bobbin, which may be of a well known construction and provided with an enlarged cone-shape end 13, see Fig. 2, has frictional relation with the spindle so as to rotate with the spindle.

`The spindle 12 is mounted at one end in a projecting lug or lip 14 which is preferably made integral lwith the end member or plate 15 which constitutes a portion of the frame of the winding mechanism. The lip or lug 11i is preferably arranged at van inclination, as more clearly shown in dotted lines in Fig. 1, so that the end which receives the end of the spindle, and therefore is provided with a spindle-receiving opening, will lbe disposed at a distance removed from the plate or frame-portion 15. The lip 14, however,

`extends inwardly from the frame-portion 15 `just suflicieiit to provide secure support for the end of spindle 12 when the latter is in normal position shown in Figs. 1 and 2; the normal position bein@ maintained by yielding means later described, which permits the spindle to be moved in a longitudinal direction so as to enable the end of the spindle to be withdrawn from the lip and swung laterally, by reason of its mounting later to be described when it is desired to remove the bobbin.

The frame of the winding mechanism is rotatably mounted in suitable brackets or standards 16, 16; and this frame consists of the end plate 15 and the opposite end plate 17, both of which are provided with hubs or projections; the end plate 15 being provided with the hub 10 while the end plate 17 is provided with the hollow hub 18, both of which areintended to be mounted in suit- Fable bushings, as shown at 19 and 20, re-

spectively. The end of the hub 10, which extends beyond the standard or bracket 16, is provided with a pulley 21 which is adapted to receive a driving belt from a suitable source of power; the pulley 21, in practice, being adapted to be driven at substantially the same speed as the speed of the twisting head from which the yarn is being received and also in the same direction as said head, in order to maintain the twist in the yarn given thereto by the twisting meehanism.

The end members lor plates and 17 are maintained in proper relation withl each other by the longitudinal members or rods 22, 22 which are suitably7 secured to the end plates. The end members or plates 15 and 17 also provide bearings for the ends of two screw-rods 23 and 24 which are rotatably mounted in the end plates. In order to give suiiicient rigidity to the frame, the opposite ends of the two end plates 15 and 17 are also shown provided with the longitudinal member or rod 25. The screw-rods 23 and 24 are preferably located intermediate of the vertical pla-nes of the frame members or rods 22, 22 and on the same side of the longitudinal center line; all of the last mentioned rods being suitably spaced apart so as to accommodate the yarn controlling mechanism later to be described. One end of each screw-rod is shown extending through the end plate 17; and the end of screw-rod 23 shown provided with a pinion 26 arranged in mesh with a pinion 27 secured to the end of screw-rod 24. The screw-rod is also provided with a belt-receiving pulley 28. With the screw-rods operatively connected with each other by means of the pinions 26 and 27, it is evident that the rods will rotate in unison but in opposite directions. The pulley 28 is disposed in alinement with a dead pulley 29 ar ranged on the end of bushing disposed about the hub 18. Pulley 28 and dead pulley 29 are intended to be operatively connected by means of a suitable belt, indicated at 30, whereby rotation is imparted to the screw-rod 24 when the mechanism is in operation, namely when the spindle-carrying frame is rotated by means of the power imparted to pulley 21, thus causing pulley 28 to be moved through an orbit about dead pulley 29.

Spindle 12 is pivotally secured at 31 to, an extension or trunnion 32 which passes vthrough the hub 18. The hub 18 is shown counterbored to receive the end of a coil spring 33 which encircles the extension or trunnion 32 and bears against the end portion or head 34 formed on the inner end ot extension 32. The spring 33 tends to press the spindle, with the bobbin, toward the right in Figs. 1 and 2 and yieldingly mailitain the opposite end of the spindle 12 in the opening formed in the lug or lip 14 at the yarn-receiving end of the winding frame.

The extension 32 of the spindle passes entirely through the hub 18 and is provided with a pulley 35 which is preferably loosely mounted thereon. The extension 32 is shown reduced at the outer end so as to provide a shoulder against which pulley bears and has frictional relation therewith; the frictional relation being controlled and maintained by means of a coil-spring 3G which encircles the reduced end of extension 32. The tension of the spring 3G is controlled by a nut 37 which screws onto the threaded end of the extension 32. Pulley 35 is intended to receive a belt, indicated at 38, which is adapted to be' driven troni a suitable pulley on a countershatt located in the lower part ofthe, frame, but not shown; the belt 38 being arranged to rotate the extension 32, and therefore the spindle 12 in the same direction as the spindle-carrying frame is driven by means of a belt passed about pulley 21. The bobbin-'holding spindle, in practice, is rotated at a faster speed than the carrying frame in order to wind the yarn on the bobbin.

Slidably mounted on the two connecting rods 22, 22, which are arranged ou the same side of the longitudinal center line of the carrying-frame, is a traveling threader or guide, comprising a block or member 39, which is also provided with openings extending transversely therethrough for the passage of the two screw-rods 23 and 24. These openings are suiiciently large to pre vent actual Contact between the block and the screw-rods, thus permitting the screwrods to rotate without in any way affecting the position of the block or member The block or member 39 is provided with a transversely disposed slot of a depth slightly beyond the point where the screw-rods 23 and 24 pass through the block, as indicated at 40 in Figs. 3 and 4; and this slot is adapted to receive the screw-rod engaging members 41 and 42, respectively. The screw-rod engaging members 41 and 42 are identical in construction, but oppositely disposed; each being provided with a bayonet-slot formation, as more clearly shown in Fig. 6,

-with one end of the slot made arcuate, as

shown in Fig. 6, and threaded or provided with `a screw-thread engaging portion 43 adapted to engage with the threads of the respective screw-rods. The screw-rod engaging `means preferably comprises the two members 41 and 42 shown, which are adapted to slide transversely of the block or head 39 in a slot-way 40, which enables them to be moved into and out of operative relation with their respective screw-rods; in other words, when the blocks are moved transversely ofthe slot 40, so as to bring the end to is Vpreferably secured on the upper sur# faceof the block or member 39 and, in the particular exemplication, comprises a link 46 pivoted at one end to trunnion 45 of` member 41, vvhile the other end of the link 46 is pivotally secured tothe ends of links 47 and 48. Link 47, in turn, is pivotally secured to a member or lever 49 Which is piv` oted at 50 on the block or head 39; the pivotal point 50 being at .an intermediate pointa betvveenthe ends of `member or lever 49;`

with the pivotal point of link 47 arranged at one end of the lever and therefore to one side of the pivotal point 50, as clearly shown in Fig. 3. Pivotally secured to the trunnion 45 of member 42 is a link 51, the opposite end whereof is pivotally secured to links 52 and 53. Links 52 and 48 have their adjacent ends pivoted on a pin or projection 54 formed on the block or head 39 so as to provide a fixed pivotal point; While link 53 is pivotally secured to the member or lever 49 on the opposite side of pivotal point 50 from that 'Where the pivotal point of link 47 is located.

As `is evident from the construction shovvn and described, When lever 49 is oscillated about its pivotal point 50, it will actuate the double toggle-lever mechanism Which has operative relation with the elements or screiv-rodengaging members 41 and 42. As shown in Fig. 7, the screw-rod engaging portions of the sliding members 41 and 42 are arranged at the outer ends and therefore adjacent opposite sides of the head or block 39, so that it Will require a movement of the sliding members toward the longitudinal center line of the block or head 39 to bring the members into operative engagement With` their respective screw-rods.

With this arrangement therefore, it is apparent that when the free or outer end of member or lever 49 is swung to the left, as

' shown in Fig. 3, link 53 will induce a contracting movement of links 51 and 52, due to the fixed pivotal point 54 at the end of link 52. This vvill cause member 42 to be moved along the slot-Way 40 in the head 39 so as to bring its screw-engaging portion 43 into threaded or operative relation With .its adjacent screvv-rod 24. During this `operation, `the opposite Aendof member or lever f 49, through the medium of link 47, ivillforce links 46 Aand 48 into a disteuded relation,

rod24, or rather, to follow the lead of the namely substantially into alinement with each other, as shown in lfigl 3, because of `the fixed pivotal point 54 at the end of link screvv-threads- In order to induce movement of the head 39 inthe `opposite direction, it Will be necessary to swing member or lever 49 toward the right in Fig. 3, and thereby induce member 41 tobe dravvn in- Wardly and into operative engagement with its sorevv-rod 23, at Which time member 42 will be forced out of operative relation with its `screWrod 24. With this situation, the block 39and elements carried thereby Will be forced to travel in the direction of rotation or lead of the threads of screw-rod The outer end of member or lever 49 is shown slotted or bifurcated so as to provide the `tivo separated projecting portions or prongs 55 and 56.

Pivotally mounted on the lower side of the block 39 is a yoke member 57 arranged transversely of the 'block 39 and provided at an intermediate point with a roller 56. The ends of the yoke are trunnioned on the block 39 at the point 59, and one of the ends arranged to extend about the side of the block 39 andfgiven the spider formation or Widely separated bifurcations shown at 60 in Fig. 4 disposed parallel vvith the side of the block 39. Pivotally secured at 61 to the spider or bifurcated end 60 of the yoke 57 namely at a point in alinement With the pivotal point 59, is an arm 62 which is 110 adapted to extend intermediate of the projecting portions 55 and 56 of lever 49. Disposed on opposite sides of arm 62 and intermediate of the bifurcations or -spider 60, l provide a pair of springs preferably in the 115 nature of coil-springs 63 and 64 adapted to bear against opposite sides of arms 62, While the other ends of the springs bear against the arms of the bifurcations or spider 60; the springs63 and 64 being of substantially 120 equal tension and exerting pressure in opposite directions against arm 62, so that arm 6.2 Will normally be held at an intermediate point betvveen the bifurcations `60. The springs 63 and 64 are maintained in place 125 by the arcuate guide-rod 65 which is adapted to pass through arm 62 and be secured to the bifurcations l'60;the arm 4624` being arranged element or rod 65. Itis evident fromthe construction shown and described that arm 62 will be caused to constantly oscillate with yoke 57; such action or tendency maintaining while the pressure of both springs 63 and 64 remains substantially equal; compression of either spring 63 or 64 being induced by momentarily arresting arm 62 in its oscillatory movement by means later to be described.

The yoke 57 is maintained under spring pressure by means .of a spring 69, one end whereof may be seated in a suitable socket or pocket arranged in the under side of block 39, or secured in place in any suitable manner, while vthe other end is seated in a socket or secured in place at an intermediate point on yoke 57, seeFigs. 4 and 5; the spring 69 normally tending to maintain the roller 58, secured to yoke 57 in contact with the bobbin 11 mounted on the spindle 12 and therefore in contact with the yarn or thread which is being wound on the bobbin.

Secured to the block or head 39 is a yarnguiding member 66, which is shown formed in the nature of a wire, bent as shown in Fig. 3, and held against movement by any suitable means, as for example by the head `of a stud-bolt or screw 67. The member 66 comprises a downwardly disposed portion, see Fig. 2, which terminates in a turn or coil so as to provide an eye through which the yarn is threaded in its passage from the hollow hub 10 to the point where it is being wound on the bobbin. The other end of member 66 is shown bent at an angle and disposed parallelk with the side of the block or member 39 so as to eXtend across the free end of lever 49 to a point intermediate of the bifurcations and 56. This end of the member 66 terminates in a right angularly disposed portion, as shown at 66 in Fig. 3, and is adapted to extend into the path of the point or tip of arm 62, see Figs. 3, 4 and 7. The tip or end of arm 62 is preferably tapered, as shown, so as to enable it to slip past the end 66a when the arm has been put under sufficient pressure through the compression of either one of the springs 63 or 64. It is apparent that in arresting thev oscillation of arm 62, the spring rearward of the arm, relative to the direction of oscillation, will be compressed by the continued oscillation of bifurcation of the yoke and arm 62 placed under 4 considerable pressure, so that when the arm been moved along the guide-rods 22, 22 of the frame into proximity with the base of the cone, so that member 66 will be substantially in alinement with the point where the yarn is to be placed on the bobbin. The roller 58, carried by yoke 57, and the eyeend of member 66 are arranged in juxtaposition, so that roller 58 will therefore be on the enlarged or cone-portion of the bobbin. The elevation of the yoke 57 induced by roller 58 being placed on the cone-portion of the bobbin will permit a small quantity of yarn to wind on the bobbin before the tripping mechanism of the yarn-guiding head is actuated. The increasing diameter of the bobbin caused by the yarn being wound thereon, further elevatcs yoke 57 against the action of spring 69 and causes the arm 62 to oscillate until it reaches point 66a. This operation also causes the bifurcated end 60 of the yoke to the left of arm 62 in Fig. 4 to co'mpress spring 64 against the side of arm 62; the latter being momentarily held against. oscillation by the end 66u of member 66. This holding relation will maintain until the amount of yarn on the bobbin has increased to an extent where the tension of spring 64 is such that arm 62 will be caused to slip past end 66" and forced into 4engagement with projection 56 of lever 49, which causes the latter to oscillate about its pivotal point 50 in a direction which induces link 53 to distend links 51 and 52 while link 47 will induce links 46 and 48 to be moved into a contracted relation. Such movement of links 51 and 52 lwill force member 42 out of operative relation with screw-rod 24, while member 41 will be drawn into operative relation with screw-rod 23. As screw-rod 23, in the particular exempliication, rotates in the opposite direction from screw-rod 24, the guiding mechanism or head 39, with its correlated parts, will be caused to travel in the direc-tion or lead of the threads on rod 23, namely toward the opposite or reduced end of the bobbin.

As the guiding mechanism travels toward the opposite or reduced end of the bobbin, it is evident that the yoke 57 will be gradually tilted or moved downwardly through the action of spring 69 which maintains roller 58 in contact with the yarn; and such downward movement will gradually oscillate arm 62 in a direction opposite to that previously described until the arm iS arrested by projection 66a, which will place the spring 63 under tension. This condition will maintain until the spring 63 is under sufficient tension to cause the pressure exerted thereby to force arm 62 past the4 detcnt 66a. Such movement will cause arm 62 to strike bifurcation 55, thereby oscillating lcver 49 into the position shown in Fig. 3, at which time the mechanism will have forced member 41 out of operative relation With screw-rod 23, While member 42 has been drawn into operative relation with screvvrod 24. With this relation `of the various parts, the guiding mechanism or head 39 will be caused to move in a direction opposite to that induced through the operation of screw-rod 23, because of the opposite direction of rotation of screw-rod 24, namely toward the cone-end of the bobbin and therefore toward the end of the bobbin provided with the greater amount of yarn. This relation and operation Will continue until yoke 57 has been elevated to a degree Where spring 64 has been so compressed that the pressure exerted on arm 62 is sufficient to overcome the edect of detent 66, When the arm 62 will again be forced into engagement with projection 56 of lever 49 thereby causing the lever 49 to oscillate so as to operate the toggle-lever mechanisms in the manner lirst described, namely Where member 42 is moved out of operative relation with screw-rod 24 and member 4l is dravvn into operative relation With screwrod 23.

As is evident from the foregoing description and the drawings, the maximum high and maximum 10W points for the roller 58, and therefore for the free end of yoke 57 will constantly be advanced toward the reduced or smaller end of the bobbin as the amount of yarn on the bobbin increases, until the opposite or small end of the bobbin has been reached and filled; the yarn or thread, as is evident from this operation Will therefore be Wound in overlapping stages throughout the length of the bobbin.

lt is apparent that the speed of the bobbin will have to vary and be commensurate With the diameter of the portion at which the yarn is being Wound, in order to take up the yarn as it is fed to the Winding mechanism. To compensate for the difference in diameter, or, in other Words, the difference in speed necessary to continuously take up the yarn, 'I show the pulley 35 loosely mounted on they end ofthe spindle extension 32, With the pulley 35 maintained in frictional contact With the shoulder formed on the spindle extension 32 by means of the spring 63, as previously described. The tension of spring 36 is regulated by the nut 37 so as to firmly pressthe pulley 35 into frictional engagement With the shoulder of the extension 32. As the yarn is delivered from the twisting head or mechanism to the Winding mechanism at a given speed, it is evident that greater tension or draft vvill be exerted on the bobbin as the amount of yarn increases thereon and therefore the circumference is increased; and this increased tension or pull Will cause slight slippage between the shoulder on the extension 32 of the bobbin-holding spindle and the pulley 35, so that the ctake-up of the bobbin Will at all times be commensurate With the tension of the yarn and therefore of the feed of the twisted yarn thereto.

Rotation of the frame mechanism, induced by the belt which takes about pulley 2l, Will svving pulley 28 through an orbit or circle disposed about dead, pulley 29, Which will cause belt 3() to impart rotation to screw-rod 24, and through the medium of pinions 27 and 26 to screw-rod 23, as previously described. y

The block or head 39 is preferably provided With a cover-plate, as shown at 68, whereby the toggle-lever mechanisms are inclosed and a comparatively smooth surface provided so as to prevent the yarn or thread coming in contact with and adhering to the operating mechanism.
